What Is Acorus Calamus Rhizome Water?
Acorus Calamus Rhizome Water is the aromatic water collected during steam distillation of the dried underground stems (rhizomes) of Sweet Flag, a marsh-loving plant native to Asia and Europe. The distillate carries trace amounts of the plant’s volatile oils, mild sugars and natural antioxidants that dissolve into the condensed water. Sweet Flag has been valued in traditional bathing rituals and perfumery for centuries because of its fresh spicy scent and skin soothing reputation. Modern cosmetic makers capture these qualities by gently steaming chopped dried rhizomes; the vapor rises, carries soluble compounds, then condenses into a clear watery liquid that is filtered and preserved. The finished ingredient appears in toners, hydrating facial mists, sheet masks, lightweight moisturizers, after-shave splashes and calming body lotions where a soft herbal note and skin comforting touch are desired.

It contains no heavy oils or waxes that can build up inside pores so it is considered non-comedogenic. For acne or breakout prone skin this means the ingredient is unlikely to trigger new spots or blackheads.
